Help 100amp service will this be safe

[F80M4]

I just had an electrician in to add some capacity to my room. Only a 100 amp service but he added 80 amps to my room with a "pony panel". I think that's what @osowhom means when he says subpanel, right. I could have wired the subpanel 240 and used half the amps but all my equipment is 120 volt already and I grow in water so 240 is a bigger danger with pumps in reservoirs and such.
The first pic is the panel mounted below my cabinet that holds my 100 amp service. He ran the 12 gauge wire up the wall and out to the receptacles. It was easy because the panel is in my grow room. Second pic is a close up of the panel. There are four 20 amp breakers each attached to about 25 feet of 12 gauge wire with one 4 position receptacle box on the end of each run.
The third pic is a 600 watt HPS on a rain-tite intermatic timer plugged into one of the receptacles. The AC is plugged in and running on the same 20 amp circuit. The fourth pic is a close up of the same receptacle. I mounted it on a piece of 2x6 and used two 3 inch wood screws to attach the unit to a wall stud, but you can move them anywhere. After years of running extension cords; it's pretty cool.
I can post pics of the wiring if you're that brave, but I recommend finding a pro like I did.

An electrician did that? Bruhh

it still is not making sense the 80 amp sub panel still has to be 240v using both the a leg b leg and nuetral i know electricity to those that have no basic knowledge seems difficult but it really quite easy its just numbers really

you should be fine my suggestion is to feel the wires when you are running at full speed they should not be hot to the touch at all

Lol. I’ve seen panels ran with only one leg.high potential for an imbalance though and I’d never do it. It will work. It just isn’t wise

Well I'm no electrical genius if that's what you mean. All the stuff I've bought since I've started to grow is 120 volt. I was talking the cash it would take to replace the fixtures if that member had already bought them. I don't think my LEDs are convertible to 240 volt.

Most standard LED drivers will operate at either input voltage. You just need to swap the plug.

You are right on that and I could buy new plugs to do that; but it's not for me. I don't draw enough amps to require 240 volts.

So your original question is moot then?

I'm getting lost here somewhere my friend; what question are you referring to?

You wondered whether or not your LEDs were convertible to 240.

Yes you are right; I could buy the extensions and convert my meanwell drivers to 240v.

I’m in a similar boat with my 100a service. although slightly less lighting. Cooking, heating and water are all gas. Overall my load is low throughout the rest of my house and although I can’t fit what I need in the panel, I’m comfortable adding 60a to a sub panel. If the house is sold all of the associated wiring is completely separate from the household. I’m not an electrician, but I’m confident working safely in a panel.

Just be sure to remember that when your gas furnace dies and you have to run a couple 1500watt heaters to keep the place warm.

Been without electricity the better part of last week. Luckily I’m PNW not Texas, everything is still alive. Fortunately I work Hvac by trade, so a fix is generally fairly easy for me on a furnace. Certainly aware of the limitations and I’ll likely replace my dryer with gas because it’s piped in for it. Now if I could only find some #4 wire in stock. My house is fairly small so central air is only 1.5 ton so even that is only a 20a circuit.

This will be enough to run most everything. Total load will be 33.8a. I’ll be good I’m just pissed I couldn’t fit it in the panel. Used to be a 50a circuit in there for an electric stove, a 60a sub seems to be a safe bet.

if your total load is 33 amps in the new panel then use a 40a breaker instead of a 60 to make it a bit safer but it sounds like you know what you are doing for the most part.

8 guage wire will be plenty ....6 guage if your going to use a 60a breaker.
